Definitions
- the present invention relates to disposals and, more particularly, to disposals for needles and related devices.
- the needle includes a hub, an anterior needle for tissue penetration into a blood vessel and a posterior needle having an exterior elastomeric valve.
- the posterior end of the needle is penetrably inserted within a barrel having female threads for threadedly engaging the hub to retain the double ended needle positionally fixed with respect to the barrel.
- the proximal end of the barrel is to open to receive an evacuated blood collection tube having a stopper for penetrably receiving the posterior needle.
- blood will flow through the anterior needle and the posterior needle into the collection tube.
- the elastomeric valve recovers the posterior needle to prevent spontaneous blood flow from the needle.
- a phlebotomist can then insert a second or more blood collection tubes into the barrel to receive additional blood samples.
- the anterior needle Upon completion of the venipuncture procedure, the anterior needle is withdrawn from the patient. While the barrel is often reused, the double ended needle must be safely removed from the barrel without causing needle stick and while avoiding contact with any residual body fluids of the patient to prevent transmission of infectious disease.
- a conventional biohazard receptacle for needles is provided with a lid having various shaped slots to engage the needle hub. To dispose of a used needle, the phlebotomist must carefully place the exposed needle hub into the slot, grip and rotate the barrel to unthread the needle and cause the disengaged needle to drop completely through the slot into the underlying container. Since the barrels are often opaque, it is difficult to know when the double ended needle has become completely threadedly disengaged from the barrel.
- a recently available reusable safety blood collection device includes a holder for engaging the double ended needle, which holder is
- the guard includes an anterior collar for shielding the end of the anterior needle upon retraction of the holder and for supporting therewithin the hub engaging boss of the holder during use.
- Known syringe disposal devices are not well suited for receiving and disposing needles of such devices since the hub of the double ended needle is shielded by the collar and is not accessible for griping by the opposed edges of a slot, jaws or the like.
- a post mounted within a receptacle interferingly engages a rib of a conventional double ended needle hub to prevent rotation of the hub upon engagement of a rib.
- a sloping upper surface of the post encourages downward sliding movement of the needle into the receptacle upon threaded disengagement of the hub.
- a partial annular slot receives the collar of a guard for an enclosed double ended needle supporting holder and a post extending from the slot interferingly engages with a hub rib. Rotation of the guard with commensurate rotation of the enclosed holder will threadedly disengage the double ended needle from the holder whereafter the needle will drop into the receptacle.
- a pair of vertical diametrically opposed leaf springs may be incorporated, which leaf springs includes a lip for preventing upward withdrawal of the double ended needle.
- the hub engaging and supporting post assembly along with a downwardly directed chute for guiding a double ended needle into a receptacle may be of modular construction attachable to an aperture of any container.
- Another object of the present invention is to provide a post for threadedly disengaging a double ended needle from a blood collection tube holder.
- Still another object of the present invention is to provide a post for engaging a rib of the hub of a double ended needle to permit unthreading the needle from a blood collection tube holder in combination with a pair of lead springs to encourage dropping of the needle into an underlying receptacle.
- Yet another object of the present invention is to provide an annular slot for receiving a collar of a blood collection tube holder supporting guard, which collar is concentric with a post for interferingly engaging a rib of a double ended needle hub threadedly engaged with the holder.
- a further object of the present invention is to provide a receptacle mounted post for engaging a rib of a double ended needle hub to a permit threaded disengagement of the hub from a supporting blood collection tube holder and to encourage drop of the needle into the post supporting receptacle.
- a still further object of the present invention is to provide a method for unthreading a used double ended needle prior to disposal.
- a yet further object of the present invention is to provide a method for converting any receptacle to a disposal unit for double ended needles.
- a yet further object of the present invention is to provide apparatus and method for safely disengaging a double ended needle from a blood collection holder while shielding a clinician from exposure to each end of the needle.
- invention is to provide a transparent disposal for receiving a double ended needle from a transparent blood collection tube holder to permit visual inspection of the separation and disposal of the needle.

- Receptacles for used blood collection tube holders with double ended needles of the type associated with venipuncture procedures have been in existence for a period of years. Such receptacles tend to reduce the likelihood of needle stick and spread of infectious disease resulting from contact with the needles and body fluids disposed upon and within the needles.
- various problems arise in attempting to separate the double ended needle from the holder without requiring a phlebotomist to touch the needle.
- a number of devices for this purpose have been developed but each suffers from actual or potential problems which preclude repetitive fail safe operation.
- a receptacle 10 for receiving and housing used double ended needles.
- the receptacle includes a top surface 12 and a cover 14.
- the cover may be hinged along hinge line 16.
- Prongs, such as prong 18 may extend from cover 14 for looking engagement with slots, such as slots 20 formed in top surface 12.
- An opening 22 may be formed in the top surface to permit insertion into the receptacle of various items for disposal.
- a circular recess 30 is formed in top surface 12 to receive and nestingly support cylindrical anterior end 32 of a conventional blood collection tube holder 34.
- An apertured supporting surface 36 which may be partially or completely annular, is disposed at the bottom end of recess 30 to support anterior end 32 of the blood collection tube holder.
- a post 38 oriented off center within recess 30, includes a slot 40 for receiving a rib 42 formed in hub 44 of a conventional double ended needle threadedly engaged with boss 46 formed in anterior end 32 of the blood collection tube holder.
- This device includes a barrel 52 for receiving and supporting a holder 54.
- the holder includes a boss 56 disposed at anterior end 58 for threadedly engaging hub 60 of a conventional double ended needle 62.
- a spring loaded tab 64 extends from anterior end 58 of holder 54 for penetrable engagement with and translation along a slot 66 formed
- the slot includes laterally expanded anterior segment 68 and posterior segment 70 for lockingly receiving the tab to retain holder 54 locked in the anterior or posterior position.
- the axial length of holder 54 is sufficient to fully enclose posterior needle 72 to prevent inadvertent contact with the needle.
- anterior needle 74 is enclosed within the anterior portion of barrel 52.
- Anterior end 76 of barrel 52 includes a collar 78 for accommodating penetration therethrough of anterior needle 74 and at least a portion of hub 60 of double ended needle 62.
- the end of anterior needle 74 may be located within the confines of collar 78.
- receptacle 10 may be used.
- a cylindrical passageway 90 is sized and configured to receive and guide collar 78 through top surface 12 of the receptacle.
- the passageway also serves the function of stablizing device 50 during the process of unthreading double ended needle 62 from holder 54.
- tab 64 is translated along slot66 to position hub 60 within collar 78.
- a rib 61 of the hub will be used.
- post 94 slidingly engage slot 92 disposed in post 94 (92) located within passageway 90.
- the size and orientation of post 94 permits the post to extend into collar 78 of device 50 to accocmodate engagement with the hub 60.
- the holder is inserted into recess 30, guiding the anterior needle 48 through aperture 39 downwardly into adjacent slot 40 until rib 42 of hub 44
- Post 38 attendant recess 30 depends from a segment of supporting surface 36.
- anterior end 32 of holder 34 is reasonably well guided and supported during rotation of the holder to prevent skewing of the double ended needle upon partial unthreading and the act of unthreading will be enhanced.
- the recess will maintain the holder in axial alignment with slot 40 to ensure continuing engagement of rib 42 of the hub with the slot.
- Top surface 49 of post 38 is necessarily dropped below supporting surface 36 to an extent sufficient to accommodate the extending axial dimension of boss 46 and the axial positioning of a band 47 normally found in hub 44, which band segregates the ribbed portion of the hub from the threaded portion of the hub.
- a downward canting of top surface 49 is preferable to encourage sideways movement of a freed double ended needle to assist the hub in clearing the post prior to dropping into the receptacle 10.
- post 38 may extend across a chord of aperture 39 defined by supporting surface 36. Such configuration will assist in locating the hub of the needle with respect to slot 40 and minimize the likelihood of the hub missing or not engaging the post in the manner intended.
- Passageway 90 includes and is defined by a depending annular skirt 98, which skirt guides and stabilizes collar 78 upon mounting of device 50.
- a shelf 100 extends centrally into passageway 90 from skirt 98, which shelf supports post 94.
- the post may include a curved side 102 concentric with passageway 90 to define therebetween an annular slot 104 for receiving a segment of collar 78 of device 50.
- Slot 92 may extend inwardly from a flat surface 106 interconnecting opposed edges of curved side 102.
- annular slot 104 in combination with the remaining surface area of skirt 98 defining passageway 90 will permit unimpeded rotation of device 50 about its longitudinal axis (and double ended needle 62) but generally impede pivoting or lateral displacement of the device.
- the limited permissible movement of the device will encourage non binding interference between the rib engaged with slot 92 and permit ready disengagement upon dropping of the double ended needle after threaded disconnection between hub 60 and boss 56.
- bias means may be incorporated to force the needle out of engagement with the post.
- a bias means of this type is illustrated in Figure 4.
- a leaf spring 110 is disposed at the rear of a slot, such as slot 40, of one of the posts, such as post 38. This leaf spring may be formed as part of the post with its lower end extending upwardly from the lower part of the post.
- the leaf spring may replace the wall portion of the post directly rearwardly of the respective slot; the leaf spring may be formed in place of a part of the wall portion depicted in Figures 2 and 3; or, the leaf spring may be separate from the post.
- leaf spring 110 By having leaf spring 110 extend forwardly in its relaxed state, it will be forced rearwardly upon engagement of a double ended needle hub with the post. Accordingly, the leaf spring will bear against and bias the hub out of the slot.
- the double ended needle Upon disengagement of the double ended needle from the blood collection tube holder, the double ended needle will no longer be positionally restrained and the bias urged by the leaf spring will be exercised. Such exercise will cause the double ended needle to be urged out of
- Leaf spring 110 thereby contributes to release of the double ended needle to permit it to drop under force of gravity into the underlying receptacle; the drop may be augmented by the leaf spring.
- top surface 49 may be canted to further encourage disengagemnt between the double ended needle and the post.
- leaf spring 110 as shown in Figure 4, includes a lip 112 for bearing against the upper edge of the band attendant the hub of the double ended needle. Because of the bias provided by the leaf spring, the lip will be urged toward the hub for such engagement.
- a ramp 114 may be formed to force the lip laterally as the band passes therepast.
- the resulting sharp edge 116 will assist repositioning of the lip adjacent the top edge of the band of the hub upon initially unthreading of the hub.
- the lip bearing against the upper edge of the band about the hub, will then move over the top surface of the band and restrain upward movement of the double ended needle. Such restraint will be enough to completely disengage the needle from the blood collection tube holder. Once complete disengagement is effected and with the aid of the leaf spring mounted lip, the double ended needle is free to drop into the receptacle, as discussed above.
- FIG. 5 A further structural configuration of leaf spring 110 with its lip 122 is depicted in Figure 5.
- Post 94 as also shown in Figure 3, includes a slot 92 for receiving rib 61 of hub 60 in threaded engagement with boss 56 of device 50.
- the hub includes an annular band 69 disposed intermediate the plurality of ribs and threaded segment 67.
- Bias means which may be a leaf spring 120, extends upwardly from post 94 laterally of slot 92.
- the upper end of the leaf spring includes a lip 122 extending from the leaf spring toward the slot. The vertical position of lip 122 is set to permit band 69 to be placed intermediate the top of post 94 and the lip.
- the orientation of the leaf spring, in combination with the extent of lip 122, is established to ensure overlap of the lip with the band upon engagement of hub 60 with post 94.
- the band may cause the leaf (lead) spring to spring rearwardly (laterally) to permit the band, to clear the lip.
- the leaf spring will cause the lip to translate forwardly (laterally) into an overlying engagement with the band.
- Subsequent upward movement of hub 60 would result in interference between band 69 and lip 122 todiscourage further upward movement.
- lip 122 in combination with its supporting leaf spring 120 will encourage complete
- a single bendable lip or lips may extend radially inwardly to engage the hub and prevent withdrawal of the needle.
- a cylindrical wall 130 depends from top surface 12 to define a cylindrical recess for receiving end 32 of a blood collection tube holder, such as holder 34 shown in Figure 1.
- An annular base 132 extends radially inwardly from the
- cylindrical wall to support the holder.
- a cylindrical skirt 134 depends from the annular base proximate aperture 136 formed centrally of the annular base.
- the interior diameter defined by cylindrical wall 130 is approximately
- hub 44 includes a plurality of ribs, usually equiangularly spaced, extending longitudinally along the hub.
- a longitudinally oriented post 138 extends radially inwardly from cylindrical skirt 134. The extent of radial inward extension of post 138 is sufficient to interferingly engage with one of the ribs on hub 44 upon insertion of end 32 of the blood collection tube holder within the recess defined by cylindrical wall 130.
- post 138 will interferingly engage a rib of the hub to prevent rotation of the hub commensurate with rotation of the holder;
- the end of the post may be canted inwardly downwardly to serve in the manner of a ramp 140 to encourage downward sliding movement of the double ended needle.
- disengagement between the double ended needle and the holder may require application of a force more positive than that of gravity.
- a pair of diametrically opposed leaf springs 142, 144 may be formed in cylindrical skirt 134. These leaf springs may be defined by a pair of slots 146, 148 joined at the upper end by a third slot 150.
- each leaf spring is formed as a part of the cylindrical skirt while the upper end is free to flex.
- the interior upper end of leaf spring 142 includes an inwardly directed lip 152.
- the radial inward extension of lip 152 is sufficient to engage the top edge of the needle hub and interfere with upward withdrawal of the hub upon upward movement of the holder.
- Leaf spring 144 includes a similar lip 154.
- Upper surfaces 156, 158 may be canted inwardly downwardly to accomodate passage therepast of the hub upon insertion of the blood collection tube holder within cylindrical wall 130. During such insertion, the leaf springs will cant radially outwardly to accommodate transport of the hub past lips 152, 154.
- a cylindrical wall 170 extends downwardly from top surface 12 and defines an aperture 172.
- a base 174 extends radially inwardly from a part of the lower end of the cylindrical wall.
- the base defines a semi annular segment for supporting an upwardly extending semi cylindrical flange 176.
- the flange is radially inwardly displaced from the interior surface of cylindrical wall 172 to form a slot having a radial width commensurate with the radial width of collar 78 of blood collection tube device 50 (see Figures 1 and 3).
- the longitudinal extremities of the semi cylindrical flange include lead springs 178, 180.
- leaf springs may be formed as part of the semi cylindrical flange and defined by slots 182, 184.
- the upper ends of the leaf springs may include radially inwardly oriented lips 186, 188. The top of these lips may be canted downwardly inwardly to define ramps 190, 192.
- Base 174 may be terminated by edges 194, 196, which edges extend tangentially from leaf springs 178, 180 to cylindrical wall 170.
- a post 198 extends radially inwardly from semi cylindrical flange 176 at its approximate mid point. The upper end of the post may be
- collar 78 (see Figure 3) of blood collection holder device 50 is inserted within the slot defined by cylindrical wall 170 and semi cylindrical flange 176.
- Support for the blood collection tube holder device may be provided by the holder resting on surface 12 and by collar 78 resting upon base 174 or either one.
- the inward extension of post 198 is sufficient to extend adjacent the body of hub 60 and
- ramp 200 By forming ramp 200 upon the post, the upper end of the post will have little support for the hub and the hub will slide off the post. By forming the upper surfaces of leaf springs 186, 188 with ramps 190, 192, lateral outward displacement of the leaf springs to accommodate downward passage therepast of the hub is assured.
- FIG 13 illustrates a variant of the present invention usable in conjunction with any container or receptacle having a lid, which receptacle is to be employed for receiving used double ended needles.
- a module 230 includes a plate 232 having a recess 234 formed therein; this recess may be of the type shown in Figure 3 for use with a blood collection device 50 or of the type shown in either of Figure 6 or 10.
- a post 236 having a slot 238 is disposed within recess 234.
- Top surface 240 of post 236 may be horizontal, as depicted, or may be canted, as shown in Figure 3; alternatively, the post may be of the type described with respect to Figure 6 to 10.
- a circular shroud 242 extends downwardly from plate 232. This shroud serves in the manner of a guide or chute to direct disengaged double ended needles therethrough.
- Module 230 is to be used in conjunction with a receptacle having an apertured top for penetrably receiving shroud 242. Thereby, any receptacle can be used as a disposal unit for double ended needles upon attachment of module 230.
- the means for retaining the module in place may be permanent or temporary.
- a top 250 of a presently widely used receptacle is depicted.
- the top includes an aperture 252 of sufficient size to permit penetrable engagement by shroud 242.
- the length and width of plate (place) 232 supports module 230upon top 250 after penetration of shroud 242.
- the lower end of the shroud may include a plurality of outwardly biased resilient wings 254 extending downwardly from a groove 256 formed in the shroud.
- Locking means such as plate 260, includes an aperture 262 dimensioned to be seated in groove 256.
- module 230 is penetrably engaged with aperture 252 of top 250.
- Plate 260 may include upwardly extending sidewalls 264, 266, 268 and 270 to provide dimensional correspondence between the extent to which groove 256 is below top 250 with the position of aperture 262 of plate 260 to preclude vertical movement of the module and to frictionally maintain the module at a predetermined location within aperture 252.
- top 250 having a particularly configured aperture 252 corresponds with a widely used type of receptacle
- module 260 may be used with any receptacle having an aperture sufficient in size to penetrably receive shroud 242 and permit locking the module in place with a plate, such as plate 260.
- Blood collection holder device 50 illustrated in Figures 1, 3 and 5, was developed by Medical Safety Products, Inc. for the purpose of eliminating exposure of both the anterior and posterior needles of a double ended needle while handling of the holder other than during the venipuncture procedure itself. That is, after attachment of a conventional double ended needle, the device may be immediately used for
- the double ended needle may be retracted within the guard of the device in the event there will be a time lapse prior to use.
- the anterior needle is retracted within the guard to prevent needle stick and to contain any body fluids of the patient which may be on or about the needle.
- the posterior needle Prior to retraction, the posterior needle is shielded by both the holder and the guard.
- the posterior needle Upon retraction of the double ended needle, the posterior needle remains shielded within the holder to prevent needle stick or contact therewith by a clinician.
- Passageway 90 Figure 3 or the slot adjacent cylindrical wall 170 ( Figure 10) receives the collar extending anteriorly from the barrel, which collar may partly house and shield the end of the anterior needle.
- the anterior needle Prior to and during the act of mating the collar with the passageway or the slot, the anterior needle remains shielded and accidental contact therewith by a clinician will be precluded.
- the anterior needle is interior of receptacle 10 ( Figure 1), which receptacle shields the needle against accidental contact by the clinician.
- the needle After unthreading of the double ended needle from the holder, the needle will drop into the receptacle with little possibility that the clinician can contact either the anterior or posterior needle of the double ended needle.
- the combination of device 50 and receptacle 10 provides apparatus which will completely safeguard a clinician from contact with a double ended needle during the time subsequent to a venipuncture procedure to final disposal of the double ended needle.
- Single ended needles attached to hypodermic needles have similar ribbed hubs. Accordingly, the present invention can be used to disengage such needles from their syringes.
